The group were on trial for a break-in at an Israeli-owned arms factory on 6 August 2024 at the height of the genocide in Gaza.
Keir Starmer’s Labour government only placed partial restrictions on arms exports to Israel the following month.
The activists spent 18 months on remand before their trial began in November 2025.
Jurors did not convict them of any charges despite the judge trying to limit defences available to the activists.
A spokesperson for Defend Our Juries said: “These verdicts are a huge blow to government ministers who have tried to portray Palestine Action as a violent group to justify banning it under badly drafted terrorism legislation.
“Despite government efforts to prejudice this trial, citing the allegations of violence to justify treating Palestine Action as ‘terrorists’, as if they were already proved, the jury which heard the evidence has refused to find the defendants guilty of anything, not even criminal damage.
“It shows how out of step this government is with public opinion, which is revulsed by the Government and Elbit’s complicity in genocide.”
